Abstract

The invention discloses a method for overcoming topophysis in vegetative propagation of gingkoes, which includes the following steps: taking a healthy and full-sprouted branch being without diseases and insect pests and growing at the middle upper part of a crown on the sunny side as a cutting slip; and adopting the cuttage and stumping method to solve the problem of topophysis during the vegetative propagation of gingkoes. Multiple branches generated after stumping can be directly adopted for cuttage or propagation by grafting, and the main branch can grow vertically. According to the method, the cost is low, the seedling forming speed is high, the rate of survival is high; and the problem of quick breeding of good seed sources, pedigree, clone and excellent single plant of gingkoes can be solved.

Description

technical field

[0001] The invention belongs to the field of asexual reproduction in the cultivation of woody plant seedlings, in particular to a technical process for overcoming the position effect of ginkgo asexual reproduction. Background technique

[0002] Ginkgo biloba is left over from the Quaternary glacier movement, the oldest living fossil and relic plant known to the world among the existing seed plants. It is a special product of our country and is a national second-class protected tree species. The whole body of Ginkgo is a "treasure", which integrates edible, medicinal, economic, ecological, and cultural values. It is the most typical special multi-purpose tree species. China is not only the origin of ginkgo cultivation, the ancient center of introduction and domestication, but also the country with the richest ginkgo resources and species diversity and the largest production and export volume in the world. It has been cultivated in more than 50 countries in th...
